摘　　要：用激光拉曼光谱系统研究了含钛钡硼硅酸盐玻璃的结构。结果表明ＴｉＯ２含量较低时Ｔｉ４＋主要处于［ＴｉＯ４］中。当ＴｉＯ２摩尔含量约为２０％时，有少量［ＴｉＯ６］形成。当玻璃中Ｔｉ４＋和Ｂ３＋共存时，Ｂ２Ｏ３含量的变化不会改变Ｔｉ４＋的结构状态。但ＴｉＯ２的存在将促进部分Ｂ３＋由［ＢＯ４］转化成［ＢＯ３］，并将这一现象称为“钛硼结构效应”The structure of barium borosilicate glasses containing titanium is studied systematically by laser Raman spectroscopy. The result shows that the Ti 4+ is mainly in the tetrahedra when the content of TiO 2 is lower. Furthermore, a small amount of octahedra is formed when the mole content of TiO 2 is about 20%. When Ti 4+ and B 3+ co exist in these glasses, the structural conformation of Ti 4+ is not altered by changing the B 2O 3 content. On the other hard, the existence of TiO 2 will transform a part of B 3+ from terahedra to triangular. We call the phenomenon “The Titanium Boron structural Interaction Effect”.
